Specification of Letters Patent.

Patented Oct. 18, 1921.

Application led May 24, 1921. Serial No. 472,228.

To allwhom'z't may concern:

Be it knownthat We, RAFAEL E. Giimwn and RAYMOND JOHNSON, .citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Bumper, of whichthe following is a specification.

This invention relates to improvements in bumpers, especially adapted for automobiles, and its object is to provide a bumper which may be quickly and readily attached to or detached from the automobile frame.

Another object isl to provide a bumper with' the supporting means comprising a supporting member and a head hingedly connected thereto with the two members drawn together to rigidly clamp the bumper bar between them.

A further object isto provide a bumper with a supporting means comprising two' members contoured to hingedly interlock together for relative movement wherebyv upon drawing 'the members together thev this disclosure and which illustrate a pre-v ferred form of embodiment of the invention.

n Of the drawings:

Figure 1 is a plan view of the front portion of an automobile with our improved bumper attached thereto.

Fig. 2 is an enlarged elevation of the bumper and the forward end of they automobile frame, the bumper'bar being shown in section. Y

vFig 3 is an enlarged section on line v3- of Fig. 1.

Fig. 4 is a section on line :r4-, Fig. 2.

The bumper consists of a pair of supporting devices attached to the opposite frame beams of the automobile, and a tubular rearwardly as is the usual practice with this ty e of bum er. a. if P Y As t e supporting devices'are of duplicate structure a detailed description of one thereof will herein be suiiicient. Each of such devices as a means for supporting the bumper bar, comprises a flat spring supporting member 1 having its rear end curved to conform to the shape of the frame. beam of the machine and is attached thereto bv a shackle bolt 2 of any standardor specific construction, it being evident that various forms of bolts or other clamping devices may'be used as such do not have particular bearingupon the presentinvention. The supporting member may have, if desired, an indent 3 to engage over a rivet lieadon the frame beam of the machine if such rivet headis present.

The supporting member 1 extends forwaidly and upwardly to an approximately vertical plane, and its free end. is provided witha hooked nosefl and an adjacent portion curved to fit the bumper bar, and spaced from said curved portion is an aperture` 5 to accommodate a clamp bolt. A head 6 is provided with a transverse opening 7 to receive the bumper bar 8 said head beingI split at 9 to provide opposed ends 10, 11'.y

The inner peripheral wall of the end 10 is provided with a pocket 12 and the ad- ]acent wall surface is grooved to .form side Hanges 13. The free end of thesupporting member 1 is positioned i-n the groove between the flanges 13 with thehooked nose 41'engaging in the pocket V12,- and a clamp bolt 14 `engages through the aperture 5 and is screiv-threaded into the kend 11 of the head.

A tightening of the clamp bolt 14; will draw the two memberstogether to grip the bumper bar between them, the head 6 in this instance functioning as a lever of the second class in which the hookedend of the supporting member 1 constitutes the fulcrum, the end 11 constitutes the power end of the lever, and the intermediate portion constitutes the resistance portion of the lever. This construction provides a two-part Y hingedly united supporting means in which each ofthe members engages the surface of the bumper bar and by a tightening of the bolt 14 are positively drawn together to frictionally grip the bar.
